Abstract

119,346. Joseph, S. Dec. 7, 1917. Drills; reamers.-A tubular support a, for a small drill f is made compressible, preferably by having one or more slots b in its upper portion, to allow the chuck g to grip the drill. The lower end of the support may be hardened to form a depth gauge. The support may be used for reamers, in which case the hole is tapered.
